really depends on cam & piston choice as far as having to open piston reliefs.like scott said,most aftermarket pistons have reliefs large enough for bigger valves.

We just sent a client home to PA, that pushed 108.7 ft/lbs @ 3500 rpms, SAE, on our Dynojet, with the 26's @ 9.6 cr, in a 98"er, our Stage II heads.
He loves it.........

better off getting cams,IMO.the rocker arms would be close to twice the price of cams that would compliment the 98" CID better

It has a Andrews ev27 cam and I have the stock cv 40mm carb that has been jeted
it only has 300 miles on it. Is there a bigger cam I could be running for more power without causing any damage to my motor and should I put a Makuni 48mm carb on there or s&s super E
any advice is appreciated it as I’m stuck on what to do from here
It’s also runing a accel superfire ignition magnum wires and screaming eagle colder plugs
I heard of a wood6 or wood8 cam but not sure if that would be ok
Sorry but You should start your own thread... Maybe in the Evo classic section....
